Application filed March 20, I905. Renewed April 21, 1906. Serial No. 312.974.

To (ti/Z whom it may concern:

Be it known that I, MARY AUGUSTA HAW- LEY, a citizen of the United States of America, and a resident of Dixon, Illinois, have invented certain new and useful Improvements in Automatic Poultry-Dusting Devices, of which the following is a specification.

This invention relates to apparatus for applying vermin-destroying powder to fowls; and it comprises certain novel devices and arrangements thereof, with means actuating the same, whereby fowls in passing into and out of a hen-house are sprinkled with such powder. This application includes certain improvements to the apparatus, the subject of Letters Patents No. 472,456 of April 5, 1892, and No. 507,615 of October 31, 1893, both issued in my name.

The object of the present invention is to provide means whereby the powder to be sprinkled over'the fowls may be mechanically agitated within its container, and thereby more positively caused to percolate through its perforated base and descend over the passingfowls in the operation of the device.

In the drawings accompanying this application, Figure 1 is a perspective elevation of my improved apparatus. Fig. 2 is a detail view of the concussion device, and Fig. 3 is a detail view of the powder-container.

In the figures the letter A indicates the base of my apparatus, from opposite sides of which extend uprights A A, which uprights are contracted toward their upper ends, as at a a, and there adapted to receive and support a powder-container, as B, which has a perforated base I). The contracted portion of one of the uprights has an offset portion a, to which is pivoted a double-arm lever, as B, one arm of which has a weight, as a normally resting upon the offset a, while the other arm, which is provided with a striker a, is normally in a pendent position. A platform, as C, is pivotally mounted upon the base A, as from brackets c (2, while at a point distant from the fulcrum thus provided said platform is supported by a rod 0, which is connected at its lower end to said platform and at its opposite end is connected with said double-arm lever, being engaged with an extension of, protruding from said lever at a point intermediate the arms thereof. A push-rod D is slidably supported in a horizontal position through the container B, said rod supporting interiorly of the container an agitator E. This agitator consists of a plate having pendent teeth 6, located at a point near the perforated base of the container. The rod D protrudes-exteriorly of the container, having a head d located in the path of the striker a to be actuated thereby. A coiled spring (1 holds the rod D with its head 61 normally extended, as seen.

In the operation of my invention the apparatus being installed within the usual opening in a hen-house through which the fowls pass in entering and leaving the house, the fowls are compelled to step upon the oscillatory platform 0 in passing to and fro, as is obvious. The weight of the fowl being imposed upon said platform causes it to rock upon its fulcrum, thereby drawing downwardly the rod 0, in which action the doublearm lever B is swung in such manner that the striker a strikes the head (1, giving an impulse to the push-rod D, causing the agitator E to move across the base of the container B, moving the powder and causing it to percolate through the perforated base and fall upon the fowl. The weight a in this action has been elevated above the offset a. As the fowl prepares to leave the platform C the latter resumes its normal position through the counterbalancing action of the weight a which latter descending suddenly upon the offset a, the impact thereof shaking the container-support, while at the same time the spring d in relaxing moves the push-rod D outwardly, again causing the agitator E to disturb the powder. The sprinkling operation is of course assisted through the vibratory action of the container set up by the impact of the weight a upon the offset a. Thus the fowl in passing over the platform C is twice sprinkled in a positive and efficient manner with insect-killing powder.

Having described my invention, that what I claim is- A fowl-dusting device comprising a base, a

I declare pair of standards extending therefrom, an

offset arm on one of said standards, a powder-container sup orted by said standards, a flat, perforated ase for said container, an oscillatory platform pivoted upon the base of the apparatus, a powder-agitator within said container, said agitator'comprising a plate having pendent teeth adapted to recontainer, together with a rod connecting ciproeate across the perforated base, a springsaid platform and double-arm lever. IO held rod to support and actuate said agitator; Signed at Dixon, Illinois, this 8th day of and a double-arm lever ivoted to said offset March, 1905.
